l Application filed November 30, 1914. Serial No. 874,718.

To all whom t mag/concern:

Be it known that a citizen of d I, ALBERT E. JoiiNsoN, the United States, residing at Beverly, in the county of Essex and Stateof 5 llassachusetts, havev invented certain new and useful Improvements in Freparing l the lfollowin description enable others skilled in the art to which it appertains to make and use the same. j

This invention relates to machines for preparing soles and more particularly to a machine foi shown and 1,212,490 dated January producing the type of insole describedV in my Patent No.

ie, i917.

Boots and shoes as commercially manufactured employ a counter piece of sole shoe within leather and prevent the shoe from over?? -Inwelt shoes the size and the counter or stiffening leather in the back part of the the `upper to support the outer running length of is such that when lasting-iii, it

extends forward under the rear end of the welt.

and

the welt extends rearbreast line of the insole xtends ,forwardly a considerable distance beyond this line resulting in the-se two pieces overlapping each other from of an inch to an inch and a half.

Telt insoles are generally fitted with an edge slit, forming a with. apar forming cl lip and feather, and allele slit within the edge slit iannel and' channel flap, the por tion'between the two slits being the between substance. the upper These parts form the rib to which and welt are stitched in the inseaming operation.v .lt is customary for these cuts to be started and terminated at about the vbreast line of the insole and after the insole channeled in mens work,

upon the so as to form these cuts, the is turned and laid over between-substance. Then the outsole is laid', before the heel is secured to the shoe, th t 1oeneath ere is vat each side of the heel the outsole for a short distance luck of the breast line of the heel a substantial Yjrotuberan'ce l: s of the lip,

forme counter and welt.

d by the overlying This is d advantageous in that it prevents nailing vFee .heel on l 'the finished some Atypes evel and mars the appearanfe of shoe at the shank. Further, in of insole channeling machines difficulty is experienced in cutting in with the edge knife at the breast line in order to produce the lip, and it has been the practice to run in and out across the heel seat, but suoli practice cuts into and weakens the heelseat which should be kept as strong as possible for the reception of the heel nails.

The'object of the present invention is the provision of a machine for fitting or preparing sole blanks for use in boots and shoes in such a manner that whatever the parts used 1n the construction of the shoe may be, the heel will be ,seated level and the shank will not be disfigured.

A further object'of the invention is the provision ofl a machine whereby insole blanks may have a portion. corresponding to the feather gouged out of bothsides of the shank adjacent the breast-line in order that the edge knife of a channel machine can be set in the insole at full depth of feather in starting the channeling operation and not cut the insolein the heel seat.

To the accomplishment of these objects a feature of. the invention contemplates the provision inl a machine Vhaving a pair of sole gouging knives with a suitable table which is adjustable to vproperly position soles of different sizes for the gouging cuts. The machine is equipped with means for simultaneously adjusting the gouging knives and table in order to properly locate the gouges to be made in the sole. The table is movable relatively to the knives and has a set of markers thereon so that when the sole is brought up to the knives to be gouged the breast-line will be marked on thengrain side of the sole. After presenting the'knives to the sole the table isadvanced to feed the rsole past the knives to lengthen thegouge the desired amount. The adjusting means for setting the knives and table are operated bv a common lever which works over a scale that indicates thedifferent sizes of soles so tion of, the accompanying drawings illusd trating the bestknown mode of applying lits principle, in which: ,j

yIn the illustrated embodiment of the invention the column 4 carries aframe -6 which supports the insole gouging mechanism. VTwo vertical arms, 8 and 10 (Fig. 2) forma yoke and provide journals for the transverse shafts 12 and 14. Theshafts 12 and Y14 carry, respectively, the gouging knives 16-16 and therknife carriers 18-18, by which they are adjustedpreparatory for gouging different sizes of insoles. These knives (see'Figs. 1 and 2) are continuously rotatedon shaft 12 by a belt 20 (indicated by dotted lines in Fig. 1) running around a fixedipulley 22, on the shaft 12, overthe idlerA pulleys v24--24 mounted on theV stud 26 in a yoke 28 and then around aY power pulley at the base of the column 4. The yoke 28 is attached to the rframe 6 and is adjustable toward and from the shaft 12 by means of the bolt and slot connections 30.

f The knives 16 are connected by a spline 32 (see Figs. 4 and V5) to the shaft12and rotate therewith but are free to lmove transversely on the shaft to permit a lateral adjustment for operating on different sizes and styles of insoles. j

The gougingknives 16 are set to make a cut to the desired widthof the feather on the channeled insoleand when the insole is are atta ci. f

gouged by the knives thev cutsl are located on each side of the shank of theinsole. adjacent the breast-line. In order to vlocate the cuts at the edges of the shank of the various styles and sizes of insoles the yknives lshould be adjustable to properlyposition them for each'individual size of insole. To obtain this adjustment the knives are mount ed in the carriers 18 which slide on theshafts 14directly above the knife shaft 12. Shaft 14 is fastened against rotation by a set screw 34 (Fig. 2) and acts only as a'slide for carriers 18. VEach carrier consists of a block 36, slidable on the shaft 14, and a knife gage and plate 40 secured theretoby means of bolts 42. Each gage and plate hasv an opening 44 zu lower end to receive the hub 46 ofa f6 (see Fig. 14) and when` they l to the block 36 the knife is held between them.l The openings 44 forthe re` Y ception of the knife hubs 46 are enough ,largerA in diameter than the hubs to allow the gages 38 to be .moved relatively tothe knives in making `an adjustment for depth "it is desired to gouge the insole blank. To

adjust a gage the locking bolts42 are loosened and the slots 52 (see Fig. 1) in the 75 vgage 38 permits it tobe raised and lowered by means of a thumb screw 53 (see Fig. 2). When the gages are set the bolts 42 are tight-v ened to lock them in position. The front side of each carrier 18 is covered with a shield .54 (Fig. 1) held inplace by means of a wing-nut 56. This shield covers the knives and protects the operative from injury while gouging insoles. j

In adjusting the knives the carriers 18 are moved along the slide shaft 14 simultaneously toward and away from each other by the movement of a manually operated lever over a size scale. `The movement of thisk size lever to a particular point'on thev scale will position lthe knives for cutting a soleV the size corresponding to that position. 'The size lever'58 isjsecured to a carrier cam shaft by means of a split hub and bolt 62 so that in movement over the size scale 64 it rotates the shaft. The shaft 60 isjournaled in a pair of brackets 66 whichfrise from the back of the frame6 and project forwardly to meet the yoke arms 1Qrand 8.

The bracket 66 to the left in Fig. 2 is in# 100` .the bracket66by means of bolts'70. The castv105 ing 68 has a slot 72 through which the han- Y dle of the size lever y58v projects and the size lever` handle has a spring pressed plungerY 74 which registers with openings :7 5 on the scale 64 corresponding to the various sizes. 110 Fixed on the shaft 60 by set screws 76 are a pair of segments 78 (see Fig. 1) having cam grooves 80 one for operating each 'carrier 18. Rollers 82 mounted upon studsV 84 in the blocks 3 6 of the carrier work in the cam 115 grooves. These cam grooves are formed in the segments 78 along intersecting inclined planes (see Fig. 2) so that when the-shaft is rotated by the size lever 58 the carriers ,ing knives for different sizes of soles, isalso employed foradjusting the-fedge and Vheel gages mounted upon awork table inl order, e

*to properly position an insole for the gougying operation.

y K Thednsole 'edgeVV gagesY 82 (Fig. 4) are attached Vone to each ofthe abutments 48"on the gages 38' so thatada 130 V'es Vthe vframe 6.'

justment of the knife carriers adjusts the edge gages. The edge ages 82 move insole supporting blocks 84( ig. 4) that have a row of pins 86 located upon their upper face which act as a breastdine marker for insoles which are placed upon the table. The insole supporting blocks are mounted in T-shaped slots 88 in the table 90 and are connected for movement with the edge gages 82 by means of an arm 92 on the'edge gages which works in a yoke 94 on the end of the supporting blocks 84.- Vith this structure, when the knives and edge gages are adjusted by the size lever the supporting blocks are carried with the edge gages to accommodate the different widths of soles and give a support for the insole directly knives;

In locating the gouges the insoles are gaged from the heel and a heel gage coperates with the edge gages to position the sole. All of these gages are adjusted simultaneously with the adjustment of the gouging knives. `The heel gage 96 is mounted upon a block 98 which slides in a guideway 100 of the table 90. The heel gage is connected with the edge gage adjusting mechanism by means of a lever 102 (Fig. 1) centrally pivoted on a studv 104 carried by one of the brackets 66. The upper end of the lever 102 carries roll 106 which works in a vcam groove 108 ina bracket Von the rear end of the size le`verk58. The lower end of lever 102 is pivoted to a block 110 which slides in the yoke 112 on the heel gage block 98. With'this connection when the size leverl `58 is moved to rotate the'shaft60 to adjust the gougingknives yand end gages, the cam 108 acts'to simultaneously rotate thelever 98 and therebyshift the table 90.

In order to' bring the knives andinsole into cutting-relation the table may be given a vertical movement by which the insole is raised into contact with the gage abutments 48, To this end the table 90V is supported at its forward end by a toggle (Figs. 87 4 and the lower link 114L of which is pivoted to the yoke 116 on the machine frame and the upper link 118 of which is pivoted to the table carrier 120. To the knuckle vof the toggle there is pivoted the forward end of a pitman' 122 lwhich is provided at its rear end with an eccentric strap 124. The eccentric strap surrounds an eccentric 126 carried on a clutch shaft 128 journaled atvthe heel gage along the :rear end of the frame in the bracket 66.

The table carrier and table 90 are pivoted on a bolt 130 held in a bracket 132 on The forward end of the table is'connected to the carrier 120 by means of 'a bolt Vl 84vwhich'is pivoted in the table 90 at 186' and extends through a slot 138. The lspring mountedibetween the carrier and table surrounding the bolt 134 tends to keep below the gouging i lasting operation 5 cams 126 and ya source of power.

rotates it against the table in spaced relation to the carrier andis adjustable by a nut and pivot washer 142 on the bolt 184. The insoles to be gouged are positioned upon the tabl-e 90 between Ythe edge gages 82 and against the heel rage 96 and are brought up against the knives and abutment 48 when the toggle is straightened by rotation of the eccentric 126. The verticalmovement of the toggle for presenting insoles on the table to the gouging knives is constant so when the insole is forced against the abutments 48 the spring 140 provides for the different thick! ness of insoles. rlhe spring 140 is strong enough to keep the insole pressed against the abutment 48, and embed the marking pins 86 in the insole.

Vhen the table carrier brings the insole up against the knives a gouge corresponding to the shape of the periphery of the knife and of a depth corresponding to the projection of the knife below its gage is made but such a cut is not of sufficient length to take care of the extension of the counter beyond the breast-line of anv insole in the give a relative movement to the insole and gouging knife to lengthen the cut the desired amount. For this purpose the table is slidably vmounted upon the carrier 120 between guides 144 (Figs. 3, 4 and 5) at the forward end of the carrier and the carrier pivots 146.v vThe* table 90 is slotted at its ivot 130 andthe rear end thereof'carries the roll 148 which works in a cam groove 150 mounted uponv the clutchshaft 128. The cam groove 150 is so related to the eccentric cam 126 that whenv the table is raised to present the insole the cam, 1.50 moves the-table past the knives and lengthens the gouge.

During the-gouge lengthening movement of carried across theknives4 by means of the pins '86 which grip the insole when the ytable is'forced up.y Itjvill `thusdbe seen that the pins 86 have the two-fold function of gripping the insole during the feeding( movement and marking the breast-line.

The clutch shaft 128 which rotates the 150 is adapted to be connected with a driving pulley 152 connected with The pulley 152 and shaft 128 are provided with a one revolution clutch 154. This clutch is the ordinary type of Horton clutch used generally in this class of machines and for this reason is only diagrammatically illustrated herein. When the trea'dle rod 156 is forced downv it en 'gages a latch'158 (see Figs. 1 and 2) and thetension of the spring out of the path of a stop 162 on the clutch plate. When the latch 158 is released the spring 164 willrotate theclutch plate so that it isvnecessary to lli ' sizes of insoles but only one width so that when the gages are set for one Width the adjustment of the arm 58 on the scale will simultaneously set the gages and knives for all different sizes and that one Width. .In order to adapt the machine for different widths of insoles itv requires a preliminary setting lfor each width. This preliminary setting'is made by loosening the split hub connection 62 of the size arm l58 with'the shaft 60, andl if a special width in any size, say 7, is desired, the arm 58 is placed on the' scale with the plunger 74 in the open# ing opposite the Fig. 7 and* an insole of size 7 and'the'special width is placed upon the 'table against the heel gage 96 and the edge gages are broughtfinto abutment with the edges ofI the insole by means of a handwheel '166 fast on the shaft 60.j With the gages in this position the size lever is locked tothe shaft and its vmovement willV now adjust the gages and knives for all sizes of insoles andthis special Width.

The operation of themachine is-asfollows: The preliminary adjustment of the size gagesfor the width of insole having been made as described above, theheel gage may be adjustedin order to properlyl locate the breasteline of the finsole above the pins 86, by placing the marked insole of the size for which the machine is set upon 'the table between the edge gages so that the breast-.line will rest uponthe pins 86. .The heel gage can. then be properly adjusted against' the end of vthe heel by means of setscrewv166. and this one adjustment of the heel gage is lsuitabl'efory all sizes.

- With the machine in the position Vshown in Fig. 1 the insole S is placed upon theA table' -against'the gages -andi` the clutch treadle 156 is depressed to start-the shaft 128 which forces the table up against continuously rotating knives by means of the cam 126 operating the toggle vand then. the cam 150 draws the sole across the knives to give the desired length of cut. After the g combination a support for a welt insole insole is gouged the table is retracted by the cam 126 so :thatfthe gouged insole maybe removed and the parts .retracted ready for ythe neXt insole. 'Iheamountof .movement of the table to :vary `the length of gouge can be changed by using different' types of the cam-150. i l

'While the above describedmachineis intendedl primarily `for gouging insoles before they have been channeled in order lto pro-V vide a; gouge Lto sta-rt the edge knife of kthe channeling machine in, it is equally well adaptable for gouging out a portion of the lip after-,the insole has been channeled so as to properly prepare the .insole for the an insole of thevtype disclosed in the Johnson Patent No; 1,212,490', hereinbefore referred to, it will be obvious to those skilled Y in ,thevart that certain yfeatures of the invention; are of broader application andfmay be employed vin the manufacture ofv any type of sole.
